I am using Velocity Templating Language and currently have:
#set ( $stringList = $string.split(\",\") )
which works fine and splits the str
It works when I convert the array to a List using Arrays.asList() and then use methods from List to access elements.
I add the following to the context:
context.put("arrays", Arrays.class);
In velocity template I use:
#set ( $array = $getarray.getArray() )
$arrays.asList($array).get(0)
With a String-Array as follows
new String[] {"test1", "test2", "test3", "test4"};
I get the expected output:
test1
Tested in Velocity 1.6.
#foreach ($element in $string.split(";"))
$element
#end
As of Velocity 1.6, all array references are now "magically" treated as if they are fixed-length lists. This means that you can call
java.util.List
methods on array references. So, if you have a reference to an array (let's say this one is aString[]
with three values), you can do:$myarray.isEmpty() $myarray.size() $myarray.get(2) $myarray.set(1, 'test')

Its also possible to push elements into an array like this.
#set ($matchingProducts = [])
#set($bar = $matchingProducts.add($p))
